Description

The present invention relates to a rail support rail support having a flat bottom surface for mounting a photovoltaic (PV) module on a roof. The invention further relates to a clamping holder system with a support profile and with a clamping holder according to the invention and optionally with a height adapter.

The German utility model DE 20 2009 001 810 U1 discloses a solar module mounting system having a U-shaped retaining clip into which a support profile can be inserted in a tilted condition and secured by a simple linear push movement. The retaining clip has two opposing grooves that are shaped differently and have different heights. Entrance areas of the grooves have an identical height, which correspond substantially to a thickness of the support profile, so that the profile when mounting in the retaining clip must be positioned very accurately and with great care.

It is therefore an object of the invention to provide a clamp holder and a clamp holder system which overcomes the above-mentioned disadvantages.

This object is achieved by a rail support rail clamp bracket having a flat bottom with a width and to which a PV module is mounted on a roof, comprising a base member having a top and a bottom, a first clamp leg having a first Stopper portion and a first overhanging holding portion, wherein the first stopper portion and the first holding portion define a first clamping groove corresponding to a first shadow space below the first overhanging holding portion, wherein the first stopper portion, preferably perpendicular, protruding from the top of the base member and wherein the first Holding portion oriented parallel to the upper side of the base member, a second clamping leg having a second stopper portion and a second overhanging holding portion, wherein the second stopper portion and the second holding portion define a second clamping groove which corresponds to a second shadow space below the second overhanging holding section, wherein the second stop section protrudes from the upper side of the base element, preferably vertically, and wherein the second holding section is oriented parallel to the upper side of the base element, a first support element, and at least one second support element, wherein the clamping legs define a T-shaped receiving groove for the support profile between the holding portions, the stopper portions and the top of the base member, wherein the holding portions, preferably at the same height, with a clear width, which is smaller than the width of the support profile, and wherein a distance between the abutment portions is greater than the width of the support profile, wherein each support member protrudes with a height from the top of the base member, so that the support elements together define a support plane for the underside of the support profile which is oriented parallel to the holding portions, wherein at least one of the support elements is arranged outside the shadow spaces in an intermediate region of the upper side of the base member which lies between the first and second shadow space.

The clamp holder of the invention is simple. Support profiles can be mounted by oblique insertion and subsequent tilting with subsequent retraction in a simple manner in the clamp. The clamp holder can be produced by extrusion. The clamp holder can be easily mounted on the roof, z. B. by screwing.

In a preferred embodiment, the first clamping leg and the second clamping leg are equally strong.

Due to the same strong training of the clamping legs, the clamping grooves are the same height. By varying the thickness of the clamping legs support profiles can be used with differently shaped edge regions.

Preferably, each support element is designed as a rib or web. Each rib or web is preferably formed integrally with the base member and extends transversely to the clear width.

Furthermore, it is advantageous if the base element has laterally outer fastening sections.

The lateral outer attachment sections serve to attach the clamp holder to the roof.

In a further preferred embodiment, the base member is plate-shaped, wherein the top and bottom of the base member are oriented substantially parallel to each other.

If the base element is plate-shaped, it can be easily mounted on the roof. Due to the parallel orientation of the top and bottom of the base element, the support profiles are flat on the roof.

In a further particular embodiment, all supporting elements are located outside the shadow spaces in the intermediate region of the upper side of the base element.

In this case, the support profile can be introduced into both the first and second clamping grooves first (by tilting and tilting). The clamp does not need to be specially aligned during installation on the roof. When mounting, it does not matter which clamping groove is "up" and which clamping groove is "down".

Furthermore, it is advantageous if the clamping legs, the support elements and the base element are arranged and formed symmetrically to each other.

Here are the same benefits as above. Due to the symmetrical design simplifies the tool with which the clamp holder, z. B. by extrusion, is produced.

In a further embodiment, the heights of the support elements are all identical.

Identically high support elements are particularly well suited for use with support profiles whose undersides are a uniformly flat surface.

According to a further aspect, a clamping holder system with a support profile and with a clamping holder according to the invention is proposed.

In a further embodiment, a height adapter is further provided, which has an upper side and a lower side, wherein the underside recesses, which are formed and arranged so that the recesses at least the support elements, preferably form-fitting, record that in the intermediate region of the upper side of the base member are arranged, wherein the support plane is defined by the top of the height adapter.

Through the height adapter, a modular system can be formed in which different strong support profiles can be used. The support profiles may have different thicknesses in the region of their clamping sections. The clamping sections interact with the clamping grooves of the clamping holder. Furthermore, irregularities can be compensated, which go back to different thickness support profiles (manufacturing accuracy).

Furthermore, it is preferred if the height adapter has a width which is smaller than the clear width.

If the height adapter is narrower than the receiving groove, it can simply be inserted from above through the groove and attached to the support elements. The assembly is very simple.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.
